The use of logical-linguistic apparatus to describe the functioning of medical systems

Abstract

The article describes the developed medical systems. The basis of systems is the mathematical apparatus of fuzzy logic. The advantage of logical-linguistic models is their universality. The components of the model are easily upgradeable. The article discusses examples of models related to medicine. The first model is used to recognize cough sound signals. The sound signals database includes sound signals for coughing patients of a medical institution of the pulmonology department. The developed model has been tested in a hospital, and is also used in the educational process of several higher educational institutions. To develop the second model, statistical data related to the field of eye diseases were used. Based on the collected data, a model has been developed to support adoption in the diagnosis of eye diseases.

Description of the development of an experimental stand for the detection of defects in pipelines

“…The main elements of the stand (figure 1): compressor, receiver, sensors (microphones) and their connections, flexible wiring line, two main rigid underground/above-ground communications with and without defects, flexible wiring (main line) for supplying the resource to the consumer, as well as a replaceable connection main highways with a receiver. The scheme of the experimental stand and its photo are shown in figures 1 and 2, respectively [1]. The stand provides for two parallel lines, one of which is intended for observations and experiments in the absence of defects, and the other in the presence of various and multiple damage to the lines.…”

“…Regarding the implementation of the mathematical part of the functioning of the model, it should be noted that the method of multiple signal classification (MUSIC) is based on the analysis of eigenvectors [3]. The primary task is to find the coefficient optim W of the optimal vector, the elements of which are specified by the function P and the matrix R [1,2].…”
